Coastal Processes: Waves

The video explores the interaction of land and sea along coastlines, focusing on the impact of waves. Waves, generated by wind, transfer energy across the sea and break upon reaching the shore. The video explains the concepts of swash and backwash, and distinguishes between constructive waves, which deposit material, and destructive waves, which erode the coast. These processes are crucial in shaping coastal landscapes.

What initiates the formation of waves in the ocean?
